With this posting, I am starting a non-scheduled regular series of "Miscellaneous Thoughts" that have occurred to me at various times. They will be in no particular order, and if I forget , may sometimes even be repeated.  If so please forgive me. At least as the list gets longer, the old messages will be "long gone" and you won't see them unless you scroll back.

This first one is appropriate given the discussion of the various proton centers.

The other Centers of Excellence that now provide Proton Beam Radiation Therapy may be in the early stages of developing their own variations of the treatment planning and procedures, but this is as it should be. The basic requirements have been established and approved, and all must adhere to them until improvements are established by proper clinical trials, approved, and implemented. The more experience that is brought to bear on the treatment itself and the more that the treatment is used and made known, the sooner these improvements, which are inevitable, will occur.
